CONTAINER COVER.

Application filed April 7, 1922. Serial Rb. 550,278.

To all whom it may concern:

Be it known that I, ROBERT BUEDINGEN, a

citizen of the United States, residing in the city of Rochester, county of Monroe, and State of New York, have invented certain new and useful Improvements in Container Covers, of which the following is a full, clear, and exact specification.

My invention relates to containers and refers particularly to container covers.

The object of'my invention is a container cover, preferably of cardboard, paper or similar materials, which will be economical, in construction, attractive in ap earance and which will possess strength an rigidity.

The attractiveness of domed box, or container, covers makes them of particular value, especially in those industries in which artistic effects are desirable.

The construction of such covers possesses numerous manufacturing difiiculties when strength and rigidity are requirements.

Container covers of this character when produced by cementing, or gluing, a flat top to the side member and then doming it by pressure, are extremely weak, as any pressure brought to bear upon the domed top will cause the top to break away from the side because of the outward strain upon the glued points of contact, and the same weakness is experienced in covers formed by cementing a domed top'to the side member.

My invention overcomes these objectionable features and presents a method of producing container covers possessing great strength, which, at the same time, can be easily and economically constructed.

My invention comprises a plurality of elements of such size and shape, and of such arrangement, that an inward pressure upon'the top is compensated by supporting means resisting the outward stress due to such pressure.

In the accompanying drawings, illustrating oneformof a device of my invention,

similar parts are designated by similar numerals.

Figure 1 is a vertical cross-section of a number of elements of my invention, shown in position for assembling.

Figure 2 is a perspective viewof the elements of Figure 1 in assembled position;

Figure 3 is a perspective view of one element of my device, partially folded to show the reverse side.

Figure 4 is a to plan view of my completely assembled evice.

Figure 5 is a vertical cross-section of my finished device.

For purposes of readily showing its formation, the drawings show the cover in an inverted position from that in which it is used as a container cover.

The various elements of the container cover of my invention are clearly shown in Figures 1, 4 and 5.

10 is a cylindrical cardboard side member open at both ends. 11 is an annular cardboard-supporting member capable of being inserted snugly within the side-member 10.

12 is an annular cardboard top member which has been pressed into a somewhat tray formation, having the annular flange 12, the compressed portion being capable of snug insertion within the side member 10, the flange 12 resting upon the edge of the member 10.

13 is an annular aper.member having a diameter somewhat arger than the diameter of the side member 10.

The elements shown in Figure 1 are assembled as follows The supporting member 11 has its one face covered with glue 11 and is, inserted within the side member 10. The edges of the side member 10 are inserted into a glue solution 10. The member 13 has its one face covered with glue 13 and pressed firmly upon the inset face of member 12 thus combining them. The members 10 and 11 are then pressed firmly upon the combined members 12 and 13, and the four members thus combined are laid u on an iron form and pressed, the resulting device being shown in Figure 2 in which the member 13 is pressed around and attached to the upper exterior portion of the member 10 and 15, at the same time, pressed inwardly upon the inset face ofthe member 12, the entire device now presenting'a container cover having an inset top.

The, annular paper finish member 14, having its one face 14" covered with glue and having a diameter preferably equal to the diameter of the kinset face of the member 12, is then pressed firmly upon the exposed face of the member 13, the resulting product being shown in Figure 4.

The device thus produced having a flat inset top is then p aced in a dommg and shaping form under pressure and heat, whereby the top is pressed outwardly form ing a dome, the device being shown in Figure 5.

The device of my invention, constructed as above, is attractive in appearance and of great strength and resistance.

It will be noted that any inward pressure brought to bear upon the outside of the top will be ofiset and resisted because of the practical abutment of the supporting member 11 upon the inner face of the side member 10 and also because of'the abutment of the top member 12 upon the upper inner face of the side member 10.

While the supporting member is not absolutely essential, I prefer to employ it because of the added strength and rigidity to my device.

It will thus be seen that my invention presents an attractive, economical, strong and effective container cover.

I do not limit myself to the particular size, shape, number, composition or arrangement of parts, as shown and described, which are mentioned simply as an example for the clear explanation of my invention, and all of which may be changed without going beyond the scope of my invention.

What I claim is 1. The process for producing container covers which comprises attaching a paper member to a cardboard top member having an inset face capable or snugly fitting within a Side member, the paper member be ing larger than the top member, positioning the inset face of the top member within a side member, attaching the side member to the flange of thetop member and doming the top.

2. The process for producing container covers which comprises attaching a paper member to a cardboard top member having an inset face capable of snugly fitting within a side member, the paper member be ing larger than the top member, inserting a snugly fitting supporting member within a side member, positioning the inset face of the top member within the side member, attaching the supporting member to the inset faee of the top member and attaching the side member to the flange of the top member and the paper member.

3. The process for producing container covers which comprises attaching a paper member to a cardboard top member having an inset face capable of snugly fitting within a side member, the paper member being larger than the top member, inserting a snugly fitting supporting member within a side member, positioning the inset face of the top member within the side member, attaching the supporting member to the inset face of the top member, attaching the side member to the flange of the top memher and the paper member and doming the supporting member and the top.

4:. In a container cover, in combination, a side member, a closely fitted supporting member within the side member, a top member the inset portion of which is attached to the supporting member and the flange portion of which is attached to the edge of the side member and a flexible member attached to the outer face of the top member and to the outer face of the side member.

5. In a container cover, in combination, a side member, a domed supporting member fitted snugly within the side member, a domed top member attached to the supporting member and the edge of the side memher, the shoulder of the top member abutting upon the inner face of the side member and a flexible member attached to the outer face of the top member and to the outer face of the side member.

Signed at Rochester, in the county of Monroe and State of New York, this atth day of April, 1922.
